Guys, I am sorry. The answer was supposed to be 791 but it is not a prime. I based off my hints on a website. Anyway, the 4th hint was definite and I can't take anything back. Misspiggy95 wins the giveaway. I am sorry again, and I have decided to host a giveaway with my friend later today. It will be around 500 TBT. The TBT will be my friend's , I'll have none soon xD. I promise that they will not inolve maths or numbers!
